I think the base is the line with an arrow with no dimension.       (changed )

We  have a trapezoid   with  a height of  3  and one  base  of  7.2

 

To  find  the  missing  base , B  :

 

17.175  =  (1/2) (3)  (7.2 + B)

 

17.175   = (3/2)  ( 7.2 + B)

 

17.175  (2/3)  - 7.2   =  B   =  4.5 (ft)

 

 

cool cool cool
